IWDG in collaboration with Dublin Port staff deployed four moorings with CPODs attached and an AMAR last week as part of the marine mammal acoustic monitoring programme associated with the Alexandra Basin Re-developement. CPODs are click detectors, logging the echolocation clicks of porpoise and dolphins while the AMAR, supplied by JASCO Applied Sciences in Canada, will record a broad band sound from low frequency (ship traffic) to high frequency (harbour porpoise).
